I am a general contractor, and have a bet with my electrician, I wondered what your thoughts are on it. Here it is: A generator is sitting on a rubber isolation pad and is in no way Earth Grounded. A grounding stake is placed in the earth and connected to one side of a light bulb, and the other side of the bulb is connected to the Hot side of the generator. So the generator’s neutral and ground wires go nowhere. I think: this is an open circuit and will not work. The electrician thinks: electricity will flow from the generator, and to ground; which will light up the light bulb. The electrician thinks the earth is a big electricity sink sucking up all electricity. He thinks that electricity always finds the easiest path to ground. I tried to explain that electricity finds the easiest path to complete a circuit, and the only reason typical household current flows to the earth is because the power plant and power poles are also grounded. I found this back-up, http://www.allaboutcircuits.com/vol_1/chpt_3/3.html which he thinks is wrong. What are your thoughts, is one of misinterpreting? How could I explain this better to him? He asked all his journey the same question, and the whole crew thinks I am crazy.
